我一直在嘗試使用畫布功能將海龜放入 tkinter。我希望能夠制作一個(gè)海龜蝕刻素描器，這樣我就可以用箭頭鍵控制海龜。我似乎無法讓它工作并且不理解它吐出的錯(cuò)誤：NameError: name 'Screen' is not defined這是我的代碼：import tkinter as tkimport turtlewindow = tk.Tk()window.geometry("750x500")window.resizable(0,0)app = tk.Canvas(master = window, width = 500, height = 500, bg = "white")app.pack()Screen()turtle = turtle.RawTurtle(app)turtle = turtle.Screen()def k1(): move.forward(1)def k2(): move.left(1)def k3(): move.right(1)def k4(): move.back(1)turtle.onkey(k1, "Up")turtle.onkey(k2, "Left")turtle.onkey(k3, "Right")turtle.onkey(k4, "Down")turtle.listen()window.mainloop()

你必須使用
turtle.Screen()
代替
Screen()
但我看到代碼的其他問題。 當(dāng)按下鍵時(shí)，我會(huì)使用tkinter方法來執(zhí)行功能。bind()
import tkinter as tk
import turtle
# --- functions ---
def k1(event):
t.forward(1)
def k2(event):
t.left(1)
def k3(event):
t.right(1)
def k4(event):
t.back(1)
# --- main ---
window = tk.Tk()
window.geometry("750x500")
window.resizable(False, False)
canvas = tk.Canvas(master=window, width=500, height=500, bg="white")
canvas.pack()
t = turtle.RawTurtle(canvas)
window.bind("<Up>", k1)
window.bind("<Left>", k2)
window.bind("<Right>", k3)
window.bind("<Down>", k4)
window.mainloop()

就像你使用RawTurtleinstead of一樣Turtle，當(dāng)你使用嵌入在 tkinter 窗口中的 turtle 時(shí)，如果你想要它提供的方法，你需要使用TurtleScreeninstead of ：Screen
import tkinter as tk
from turtle import TurtleScreen, RawTurtle
window = tk.Tk()
window.geometry("750x500")
window.resizable(0, 0)
canvas = tk.Canvas(master=window, width=500, height=500)
canvas.pack()
screen = TurtleScreen(canvas)
turtle = RawTurtle(screen)
def k1():
turtle.forward(1)
def k2():
turtle.left(1)
def k3():
turtle.right(1)
def k4():
turtle.back(1)
screen.onkey(k1, "Up")
screen.onkey(k2, "Left")
screen.onkey(k3, "Right")
screen.onkey(k4, "Down")
screen.listen()
screen.mainloop()
在這種情況下不要使用獨(dú)立的海龜Screen，因?yàn)樗赡軙?huì)創(chuàng)建第二個(gè) tkinter 根窗口，從而導(dǎo)致稍后出現(xiàn)細(xì)微的錯(cuò)誤（例如圖像未加載。）
